4.10's were fairly common with 2.2L trucks

There were many S trucks built with the 4.10 gears. I use to see a lot of them from the '80s, but I think they were used in the '90s too.

I always heard that the 84 0r 85 s10 4x4 came out with a 7.5 factory posi with 4.10 gears but it was one year or the other.

The Yukon Duragrip is a copy of the Eaton Posi. Eaton parts will interchange with the Duragrip parts. I've used Eaton parts in the Duragrip and I've used Duragrip parts in the Eaton.

no matter, to really be sure the cover needs removed and see what is stamped.

my suggestion would be a '95-2001 Explorer rear end with trac lock.. it will fit in the S10 with a little coaxing, and the drive shaft can be adapted with parts available at Napa

90 and newer will be 28 spline axles.

i read in Chevy high performance that the 7.5 gm would hold up to 400hp before breaking. and that's why gm kept them in production for so long. Ive had 5 v8 s10's, I've yet to break one of those 7.5's.

Wheel hop will break even the best rear ends. I completely agree with that. As long as you only run street tires on this it will probably hold up all right. Don't use a mini spool on the street. Yukon makes a Duragrip that works very well, and it's rebuildable. This is a low cost differentail and it's much better than the Auburn.

ever see a white s 10 on cortez roadthat is tubbed.? Its my brothers truck.
He is in palma sola area near cortez. It has a firebird rear narrowed under it. Not the 9 inch ford I recommended, but it fit good after being cut and welded.Gear ratio was too tall for a turbo 350. Lots to consider when choosing a rear end. I guess he liked the disc brakes it had.The stock rear was trashed and not even close to being a performance unit,being a one wheel wonder to begin with(open rear).

If set up properly these rear end will handle quite a bit of abuse. First find a c-clip elminaters kit with aftermarket axles, use a solid pinion spacer, (the stock crush sleeve will collapse) and girdle cover. I have a friend that pulls the front wheels 2 feet in the air for 100' at the strip with a 355 on nitrous in a 86 I-ROC and runs low 11s.

worth beefing up stock s10 rear?

im putting thought into the shell for my motor and trans. its what should be a 350 to 375 hp 327sbc. with a pretty hard shifting tci th350. i was wondering if i grabbed ahold of an 85 or so s10- with a mini spool and the taller gears i want or "need" to run would this rear end handle any abuse? i know s10s werent exactly drag wagons. but im trying not to end up building a pro street demon (i cant afford it) lol. any insight is greatly app. thanks in advance guys! ladies???? it will only see the track a few times a yr.
